Study Notes
Blood Vessel Structure
- The tunica intima layer of blood vessels is composed of endothelial tissue, collagen fibers, elastic fibers, and smooth muscle tissue (except capillaries).
Arteries
- Elastic arteries, specifically the aorta and its branches, are responsible for conducting blood away from the heart and have the highest elasticity.
Veins
- The hepatic portal vein drains the abdominal viscera and carries venous blood to the liver for processing.
Hepatic Portal Vein
- The purpose of the hepatic portal vein is to filter the blood in the liver before it reaches the inferior vena cava.
Peripheral Resistance
- Peripheral resistance refers to the resistance to blood flow in the blood vessels.
- Increasing peripheral resistance increases arterial pressure.
- The tunica media layer of blood vessels, composed of smooth muscle tissue, helps constrict or dilate vessels, thereby changing resistance to flow.
Types of Arteries
- One of the main types of arteries is NOT "collateral arteries".
Liver Function
- The purpose of filtering the blood in the liver before it reaches the inferior vena cava is to remove toxins and waste products.
- The hepatic portal vein detour allows the liver to filter the blood and remove nutrients and toxins before it reaches the general circulation.
